| corynebacterium durum sp. nov., from human clinical specimens. | a new corynebacterium species, corynebacterium durum, was isolated from respiratory tract specimens of five human patients. the strains of this species exhibited similar morphologic and biochemical features that differentiated them from all recognized species. notably, all of these strains developed irregular and strongly adherent colonies under aerobic conditions and produced acid from mannitol and galactose. the cells are long pleomorphic rods with some filaments. this species has characterist ... | 1997 | 9336915 |
| coryneform bacteria in throat cultures of healthy individuals. | throat swabs from 113 healthy individuals from hamburg, germany, and zurich, switzerland, were investigated for coryneform bacteria with nonselective and selective media. ninety specimens contained 123 strains. surprisingly, 76% of them were strains of corynebacterium durum (47%) and rothia dentocariosa (29%). only two were strains of corynebacterium pseudodiphtheriticum, and none were strains of c. striatum, c. amycolatum, or c. diphtheriae. | 1998 | 9650969 |
| diversity within reference strains of corynebacterium matruchotii includes corynebacterium durum and a novel organism. | corynebacterium matruchotii has been the subject of numerous dental pathogenesis studies. the purpose of the present study was to resolve concerns about diversity within the reference strains of c. matruchotii through analysis of seven strains procured from the american type culture collection (atcc). analysis of whole-cell fatty acid profiles with the library generation software of microbial id inc. revealed that three types of organisms have been deposited in the atcc as c. matruchotii. these ... | 2001 | 11230408 |
| a selective medium for the isolation of corynebacterium species in oral cavities. | corynebacterium matruchotii is a microbial inhabitant in the oral cavity of humans and is associated with the formation of dental calculi. c. matruchotii forms highly specific morphological units, which are referred to as corn-cobs. although other corynebacterium species have frequently been isolated from the oral cavity of humans, their distribution has not been reported as extensively. the aim of the present study was to develop a selective medium to isolate the genus corynebacterium and exami ... | 2014 | 24971800 |
| salivary microbiota and metabolome associated with celiac disease. | this study aimed to investigate the salivary microbiota and metabolome of 13 children with celiac disease (cd) under a gluten-free diet (treated celiac disease [t-cd]). the same number of healthy children (hc) was used as controls. the salivary microbiota was analyzed by an integrated approach using culture-dependent and -independent methods. metabolome analysis was carried out by gas chromatography-mass spectrometry-solid-phase microextraction. compared to hc, the number of some cultivable bact ... | 2014 | 24657864 |
